  • Computer device, exception processing method, and interrupt processing method
    Patent number: 12664111
    Abstract: A computer device is disclosed. In a virtualization I/O procedure, a redirection apparatus in a processor is used to implement privilege level switching in a synchronization processing procedure, to directly switch from a virtualization privilege level of a VM to a user mode of a host, and perform corresponding exception processing. In an asynchronous processing procedure, an interrupt request may be asynchronously transferred by using a virtual event notification apparatus and an interrupt controller in the processor without passing through a kernel mode of the host. In both of a synchronous processing procedure and the asynchronous processing procedure of the device, overheads generated during switching are reduced, and performance of the computer device is improved.
